| Abstract | Synthesis of semiconductor device design requires access to realistic physical models and adaptive algorithms. To demonstrate that such synthesis is feasible, atomic clusters with specified quasiparticle densities of states are designed using advanced search algorithms, and broken-symmetry quantum-well potential profiles are developed with optical response properties superior to previous ad hoc solutions.; Advanced stochastic search algorithms are introduced in the context of a guide to efficient implementation of inverse problem solving methods, and then, it is shown that automated searches of configuration space may be performed without the need to input a specific target function. Improved electroabsorption modulator designs resulting from these machine-based searches are given as a demonstration of the utility of targetless exploration.; Finally, the results of experimental testing of the asymmetric quantum well structures discovered by machine are presented, and it is established that in order to fabricate functional devices from these designs, significant improvements in the growth and measurement processes are required. |
